         3 . The composition according to  claim 1 , wherein the silane-based compound is a compound selected from the group consisting of a compound of the formula (3-1), a compound of the formula (4-1), a compound of the formula (6-1) and a compound of the formula (7-1):  
       
         
           
           
               
               
           
         
       
       (wherein, R represents a methyl group or ethyl group, r represents 2 or 3, and A −  have the same meanings as defined above).  
     
     
         4 . The composition according to  claim 1 , wherein the acrylic resin is an acrylic resin having a structural unit derived from an alkyl (meth)acrylate as a main component, and containing a structural unit derived from (meth)acrylic acids containing at least one polar functional group selected from the group consisting of a hydroxyl group, amino group, free carboxyl group and heterocyclic group.  
     
     
         5 . An adhesive obtained by compounding the composition according to  claim 1  and a cross-linking agent.  
     
     
         6 . An optical laminated film laminating an adhesive layer composed of the adhesive according to  claim 5  on both surfaces or one surface of an optical film.  
     
     
         7 . The optical laminated film according to  claim 6 , wherein the optical film is a polarizing film and/or phase retardation film.  
     
     
         8 . The optical laminated film according to  claim 6 , wherein the optical film further has an acetylcellulose-based film as a release film.  
     
     
         9 . The optical laminated film according to  claim 6 , wherein a release film is further laminated on the adhesive layer of the optical laminated film.  
     
     
         10 . An optical laminate obtained by laminating a glass base material on the adhesive layer of the optical laminated film according to  claim 6 .  
     
     
         11 . An optical laminate obtained by peeling the release film from the optical laminated film according to  claim 9 , then, laminating a glass base material on the adhesive layer of the optical laminated film.  
     
     
         12 . An optical laminate obtained by peeling the optical laminated film from the optical laminate according to  claim 10 , then, laminating again the optical laminated film on the resulted glass base material.
